MOISTENER.

Specification of Letters Patent. Patented June 13, li2@.

Application filed May 23, 1914. Serial No. 840,565.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. In,1318.)

To all whom it may concern:

Be it known that I, HERMANN KAMP, a subject of the Kingof Prussia,German Emperor, residing at Barmen, in the Kingdom of Prussia, GermanEmpire, have invented certain new and useful'lmprovements in aMoistener, of which thefollowing is a specification.

This invention relates to a moistener of that type, in which the wateror other liquid from the reservoir is supplied to the sponge or otherporous mass by means of capillary channels. According to the inventionthe porous mass is mounted in a casing of elastic material which servesat the same time as stopper for the lower end of the water reservoir.The lower edge of said stopper is flat and situated somewhat back of theouter surface of the porous mass, so that, if the moistener is placed ona surface to be moistened the. edge of the elastic stopper adheres onsaid surface and air-tightly closes the moistener. The air contained inthe moistener is forced back into the reservoir, so

that if the moistener is lifted the water is drawn into the porous massin consequence of the vacuum formed in the cavity of the stopper. A a

The cavity provided between the porous mass and the water reservoirprevents the water from. leaking from the reservoir.

In the accompanying drawings the invention is shown by way of example:Fig. 1 is a section through the moistener; Fig. 2 is an elevation of thesame; Fig. 3 is a top view of the sponge holder. The improved moistenercomprises in combination a water reservoir (1, a stopper 6 of elasticmaterial and a sponge c of india-rub her or other porous material. Theopen lower end of the reservoir a is closed by the elastic stopper 1).In the upper end of the by the sponge c. The surface of the spongeslightly projects over the lower edge e of the stopper. Between thesponge and the upper end of the stopper 6 an air chamber is arranged.

If the moistener is used, its lower end is pressed on the surface to bemoistened, so that the edge e of the stopper b comes in contact with thesurface and airtightly closes the interior of the moistener so that whenthe device is pressed close to the work, the cup and with it the spongeis compressed and thereby the air contained in the air chamber is forcedup into the water reservoir (1, whereby the pressure in this reservoirback of the water is increased. If the moistener is lifted 0d thesurface water is forced out of the reservoir by an excess of pressureback of the water so that the sponge is moistened.

I claim:

An improved moistener comprising in combination a water reservoir openat the lower end, a stopper of elastic material in the lower end of saidreservoir having capillary channels in its upper part and a cavity inits lower part which gets narrow towards said capillary channels, a fiatlower edge of said elastic stopper, and a sponge of porous material inthe large lower part of the cavity of said stopper, substantially asdescribed and shown and for the purpose set forth.

In witness whereof I have hereunto set my hand in the resence of twowitnesses.
